The Palisade Entrance, a novel fishway entrance, was constructed and tested at the Conte Lab's Fish Passage Complex. Trials were conducted with multiple species, including American shad, to determine entry rate under a variety of hydraulic conditions.

This is the set up of the solar panels at Blackwater National Wildlife Preserve that will be used to power the newly installed sap flow sensors on site. These solar panels will decrease the number of required trips to the site to change batteries and will contribute to the undisturbed data flow from the sensors.

Close up of the newly installed sap flow sensors at Blackwater National Wildlife Preserve. These sensors were installed by EESC's Justine Neville and Ken Krauss of the USGS Wetland and Aquatic Research Center in Lafayette, LA. These sensors will be used to analyze how the trees in a marsh ecosystem respond to changing ecological and climatic conditions.
